cashmusic.org/wushusport - element #markup could not be found.

After a bit of confusion, I think I know how this site
works…
But now I get the above text when I go to my public page
cashmusic.org/wushusport

I am used to working with wordpress sites and html forms
etc… but this site is very difficult to navigate if you want
to change anything after you have gone through the initial set up,
this part is very straight forward but the link to my google drive
did not activate so I had to work backwards and then I got
stuck.

Please advise, really think this is a great project to give
power to small music entrepreneurs.

What type of element were you trying to set up? E.g. email
collection, digital purchase, or..?

We're experiencing a bit of trouble with Google Drive lately. Do
you get an error message when you try to upload files? Something to
do with an "oAuth token"?

We're working with Google to resolve the issue, but in the
meantime, we encourage people to use Amazon Web Services. It's
fast, reliable, free for a year (and then just pennies afterwards)
and pretty much the web standard for storage. If you expect high
volume downloads, it's also infinitely more dependable than Google
Drive, which is only intended for people who will have occasional
downloads. Anyhow, if you'd like to try Amazon Web Services (S3),
here's our article explaining how to set it up: https://x.cashmusic.org/admin/help/s3
